GRAIN-DOOR FASTENER.

Specification of Letters Patent.

Patented July 19, 1921.

Application filed September 13, 1920. Serial No. 409,839.

To all whom it may omwem:

Be it known that I, CHARLES WING, a citizen of the United States, and having residence at Aurora, county of Kane, and State of Illinois, have invented certain new and useful Improvements in Grain-Door Fasteners, of which the following is a specification, reference being had to the accompanying drawings, forming a part thereof.

This invention relates to a grain car door and closure with means for securing the closure to the doorway in a simple effective and reliable manner, and it aims to provide a closure which will be easily and quickly removed without destroying it or damaging the door-way of the car.

The co-related parts are so arranged that the grain pressure does not strain the securing means, and the closure is so constructed that it can be readily removed, notwithstanding the considerable pressure exerted thereon by the weight of the grain against it. Other advantages will appear in the description and are pointed out in the claims.

In the drawings:

Figure 1 is a car door equipped with my improvement.

Fig. 2 is a section at the line, 22, on

Fig. 3 is a section at the line, 33, on

Figs. 4, 6 and 8 are views similar to Fig. 2, but showing certain modifications of the device.

Figs. .5, 7 and 9 are views taken at the lines, 5-5, 77, and 9-9, on Figs. 4, 6 and 8 respectively.

Fig. 10 is a detail elevation of another modification.

Fig. 11 is a section at the line, 11-11, on Fig. 10.

The drawings show a car, 1, provided with a door-way having posts, 22, which constitute the door-jambs, so called, back of which is secured the closure which is made up of several narrow boards, 3, placed one over the other to the desired height, each having a tongue-and-groove engagement with the next, thereby providing a graintight joint between the boards.

The advantage of making the closure of several separable and relatively narrow boards is that in removing them successively from the top downward, each board is subject only to the pressure of grain proportionate to its own area and measured by a de th not exceeding the height of the board.

iach board is provided at each end thereof with a fitting, such as a screw eye, 4, and the jamb supports a fitting, 5, in the form of a plate or bar. A connecting member, 6, consists of a shank bent at both ends to form hooks 7 and 8, respectively, the end portion of the former hook, 7, bein bent back to extend for a short distance su stantially parallel to the shank portion, while the tip of the book, 8, is not bent back so far but projects approximately at right angles to the shank. Preferably the book, 7, is formed in a plane which intersects the plane of the hook, 8, at about 90. By virtue of the difference in the shape of the two hooks, it Will be seen that when both of them are engaged with suitable fittings, placing the shank portion of the connecting member, 6, in tension, the member can swing about the hook, 7, for disengagement of the hook, 8, but hook, 7, having its terminal portion substantially parallel to the shank, can only be separated from the fitting which it engages after the other end has been freed from its fitting to permit rotating the plane of the book, 7.

The hook or bent portion, 7, as shown in Figs. 1, 2 and 3, is introduced in a slot, 9, in the fitting, 5. The width of this slot, 9,

is sufiicient to permit withdrawing of the bent portion, 7 upon rotating its plane into line with the slot, but it cannot be withdrawn while the hook, 8, remains engaged with the screw eye, 4. While the car is in transit the several hooks, 8, are retained in engagement with corresponding screw eyes, 4, by means of cleats, 10, having notches, 11, arranged to embrace said hooks, 8. These cleats will be placed in position after the boards, 3, of the closure have been assembled up to the desired height, and secured in place by connecting members, 6. The cleats will then be lightly nailed to the boards, 3, as indicated at 12, and will remain in position until it is desired to unload the car.

The slots, 9. it will be noticed, as shown in Fig. 2, are spaced quite close together so that boards of different heights may be used with assurance that there will always be one of the slots at a convenient position to receive a connecting member, 6, for holding the board in place. To further insure this the slots may be of definite length, or even one continuous slot may be formed as by placing two flat bars properly spaced as indicated at 14 and 15 in Figs. 1 and 5.

Since the bent end, 7, cannot become disengaged from the edge of the slot, 9, while the hook is held in position by the cleat, 10, it is apparent that the bar, 15, might be dispensed with, as in the arrangement shown in Figs. 6 and 7 where. the bend, 7, simply engages the edge of the fiat bar, 16, said edge overlying a recess, 17, such as is provided in all the forms 'to accommodate the bend, 7.

A single member functioning as the member, 16, may be rounded instead of fiat; this arrangement is shown in Figs. 8 and 9, wherein the member, 18, is lodged within a recess, 19, whose dimensions are such that the member, 18, and the bend, 7, are both accommodated.

However, the fitting on the jamb need not extend the entire length of the opening to be closed, but may consist of only small circular plates each having a semi-circular opening as shown in Figs. 10 and 11, where the fitting, 20, is secured in position over a small circular recess, 21, in the jamb, 2, and the bend, 7, of the connecting member 6, engages the straight edge of the semi-circular opening, 22. i

In the construction last described it will be seen that it would be comparatively easy to convert any car, while on the road, by simply boring holes with an auger to the proper depth, to produce the recesses, 21, and then placing the fittings, 20, in position over and concentric therewith. The fitting, 20, in this case is preferably made with a chamfered or beveled edge as shown, to offer minimum obstruction in the doorway.

I claim:

1. A grain door fastener for cars comprising a fitting attached to the jamb, a fitting secured to the closure, and a connecting member having ends adapted to be engaged with said fittings respectively, both ends being hook-shaped, but one of them having its terminal portion extending substantially parallel to the shank, while the tip of the other hook projects transversely of said shank; and means removably secured in position adjacent the latter hook for holding it in engagement with the fitting.

2. In the combination defined in claim 1, the two hooked ends of the connecting member being formed in planes approximately at right angles to each other.

3. In the combination defined in claim 1, the fitting attached to the jamb, being a metal plate having an edge exposed outwardly away from the closure to receive the first described hook of the connecting member.

4. In the combination defined in claim 1, the fitting on the closure being an eye standing in a plane transverse to that of the door way.

5. In the combination defined in claim 1, the last described hook engaging the fitting on the closure, and the means which retains it in engagement being a fitting secured to 'the closure and formed with a notch to accommodate the hook and the fitting.

6. In the combination defined in claim 1,

.the fitting on the j amb comprising a metal- August, 1920.
